摘要
采用热模拟技术测定出首钢研制开发的高强度船体用钢焊接连续冷却转变曲线(SH-CCT图),获得了高强度船体用钢焊接粗晶区热影响区组织变化规律,结果表明,首钢生产的高强度船体用钢淬硬倾向和冷裂敏感性较低。
The continuous cooling transformation curve of high strength ship steel developed by Shougang Group was measured by thermal simulation technique and the variation of the coarse grain microstructures in HAZ of high strength ship steel was obtained.The result indicates that the harden quenching tendency and the cold cracking susceptibility of the high strength ship steel are fairly low.
